rdbm - a reliable database library

(Note: This is from 2002 and has not been updated since. The code is
buggy, do not use!)

The idea behind rdbm is to take cdb
and put a journal before it. Then provide an abstraction layer that
looks like ndbm(3)
and writes updates to the journal. Read operations are answered by
consulting the journal and the cdb file. The result should be a
reasonably small yet crash-proof read-write database.

I implemented this in 1999. Part of the package is a server process
and a network client abstraction layer that again looks like ndbm but
consults the server for all operations, to provide multiple writing
processes.

Unfortunately, the in-memory data structure I used for the journal back
then was broken. Someone brought this to my attention in 2000, but I
lost my uni account and couldn't update the old rdbm page. Since then,
rdbm is pending a rewrite. Please don't use it before I rewrote it!
